Siux Fenix Pro Black 2026 Leo Ausburger

Siux Fenix Pro Black 2026 Leo Ausburger is a heady attack-first racket with a hard, direct feel. It wants you hitting above shoulder height, taking the net, and finishing points before they get messy.

The interesting part is that it is not just a blunt smasher. For a diamond shape, I find it more manageable than the profile suggests, with enough control to keep the ball where I want it when I’m not forcing the issue.

Technical analysis

Shape & balance

The diamond shape and pronounced head-heavy balance set the tone immediately. This is a racket that loads the upper part of the court and rewards players who are comfortable living on offense. If you like to press with volleys, punish short balls, and go after the smash, the geometry makes sense.

What it does not do is hide your mistakes. In defensive phases, the balance can feel demanding if you’re late or lazy with preparation. I still think it is more maneuverable than some diamond rackets with this much power, but it never fully loses that forward-leaning character.

Materials & construction

Siux pairs a fiberglass frame with 12K carbon on the faces and an EVA core, and the result is a crisp, dry feel. The contact is firm. The ball does not sink in much, so you get a fast, immediate response rather than a plush one.

That construction helps explain the racket’s aggressive behavior. The face texture and carbon layup give it plenty of bite, so I can get heavy spin on attacking shots. The trade-off is forgiveness. Off-center hits are punished more than with easier, softer frames, and that becomes obvious when the point speeds up.

On-court feel

Baseline play

From the baseline, I like it more on blocks and quick counters than on relaxed defense. It gives a clean rebound when I meet the ball early, and the sweet spot is bigger than I expected for a diamond, so it does help on awkward exchanges.

Still, this is not a racket that makes you lazy. Defensive lobs need proper timing, and when I get stretched out, the hard response can feel demanding. If your back-court game relies on easy ball output, this will ask more of you.

At the net

This is where the Fenix Pro Black starts making sense. Volleys come off with authority, and the racket feels stable when I’m accelerating through contact. It rewards compact, committed hands. Fast blocks are very solid too, which matters a lot in fast hands exchanges.

The downside is that it is not especially friendly on slow preparation. If the ball sits up and I’m a fraction late, I feel it. The racket wants sharp timing and an active wrist, not passive guiding.

Bandeja and víbora

These two shots are the most revealing. The racket can hit them well, but it does not hand them to you. I need a quicker arm and cleaner technique to get the best out of the bandeja and víbora, because the frame feels a little slow if I try to cruise through the motion.

When I’m on time, the spin and depth are there. When I’m not, the response feels heavy and the shot loses its usual threat.

Smash

This is the racket’s natural language. The smash is where the power shows up most clearly, and it has the kind of extra punch that can change a point fast. I also get a very direct contact that helps me commit without wondering whether the ball is going to die on the face.

Conclusion

I see this as a serious attacking racket for players who already control their mechanics and want something with real finishing power. It suits an aggressive net player who likes to dictate with volleys, fast blocks, and overheads.

What you trade off is comfort and forgiveness. It can be demanding in defense, and bandejas or víboras need cleaner timing than on easier frames. If you want a hard, powerful racket that rewards precise hands more than lazy swings, this one makes sense.
